Post workout laugh

Years ago I went for a run to my girlfriend’s apartment. When i got there i was sweaty and out of breath. I asked her if she wanted to laugh.

She said yes.

I pulled down my athletic shorts and showed her how much working out shrinks my genitals. She let out a loud laugh. I am actually quite large when hard, but I am a grower and after the run, my normal 3 inch soft dick was about 1.5 inches and my balls, which are actually well below average were tight in my scrotum both combined about the size of a ping pong ball.

The story doesn’t end here though. She has a loud high pitch voice and her prudish roommate came running out and got a good view of my tiny shriveled cock.

She laughed and blushed and gasped. Then just turned around and walked away.

From that point forward, she greeted me with a grin and a chuckle.

I'm young at this point in my life and need to prove myself, so on future visits I try to tell her how big I am and even asked my gf for backup. All she would say is your size isn't important to me as they both laughed.
